When the device is needed to treat straw pulping waste water (for convenience of description and understanding, waste water is used to replace straw pulping waste water), workers inject waste water into the feed hopper 501, waste water in the feed hopper 501 enters the feed pipe 502, then the waste water moves downwards along the feed pipe 502, then the waste water enters the upper cavity of the rotating shell 6, then the waste water enters the treating shell 2 through the four discharge holes 10 at the upper side, in the process that the waste water moves downwards in the feed pipe 502, when the waste water passes through the turbine 7, the turbine 7 starts to rotate anticlockwise (overlook direction) under the impact of the waste water, the turbine 7 drives the connecting columns on the turbine 7 to rotate anticlockwise together, the connecting columns of the turbine 7 drive the four arc plates 8 and the middle plate 9 to rotate anticlockwise together, and the rotating arc plates 8 squeeze the waste water in the adjacent area in the rotating shell 6, so that the rate of the waste water entering the treating shell 2 is improved, and the efficiency of waste water injection is improved.

As the foam slag continuously floats up, when the foam slag floats up to the liquid level surface, the mixed liquid continuously rotates under the action of the stirring blade 1503, so the foam slag also rotates clockwise, when the rotating foam slag contacts with the scraping plate 1504, the scraping plate 1504 starts to press the foam slag in the adjacent area leftwards and moves leftwards until the foam slag enters the slag collecting shell 3, as the mixed liquid continuously rotates, the scraping plate 1504 continuously scrapes the foam slag into the slag collecting shell 3 until the foam slag is not generated in the mixed liquid, in the process of removing the foam slag, the displacement sensor always records the thickness of the scraped foam slag, after the foam slag is scraped, the total thickness of the foam slag is transmitted to an external control module in the form of an electric signal, then the external control module controls the amount of a flocculating agent released next time by the water pump 1302, so that the amount of suspended matters in wastewater is matched with the amount of the flocculating agent, the material loss is reduced on the premise of ensuring that the wastewater treatment is complete, after the wastewater treatment is completed, the worker starts a discharge pipeline of the treatment shell 2 to discharge the wastewater after the wastewater treatment is completed.

The straw pulping wastewater treatment device according to claim 8, characterized in that the third limit groove (1609) is a closed groove formed by combining a second arc groove (16091), a third arc groove (16092) and a second straight groove (16093) which is arranged in a mirror image, and the radius of the second arc groove (16091) is smaller than the radius of the third arc groove (16092).
10. The wastewater treatment method of a wastewater treatment apparatus for pulping by straw according to claim 9, comprising the steps of:
1. the staff starts the second motor (1602) and injects the waste water into an external channel of the shielding shell (1601), then intercepts straw scraps contained in the waste water through the interception piece (1606) which circularly rotates, scrapes off the straw scraps left on the interception piece (1606) through the cleaning piece (1608), and collects the straw scraps in the collecting shell (1604);
2. starting a water pump (1302) and a first motor (1305) by a worker, injecting a flocculating agent into the treatment shell (2) to be in contact with the wastewater and generate floccules, wherein in the process, the wastewater and the flocculating agent move upwards from the bottom of the treatment shell (2), even if the wastewater and the flocculating agent are added layer by layer, the space in the treatment shell (2) is divided into a plurality of vertical parts, and the movement space of the wastewater and the flocculating agent is reduced, so that the contact area between the wastewater and the flocculating agent is increased;
3. after the wastewater and the flocculating agent are injected, a worker closes the water pump (1302) and starts the air pressure pump (1404), the rotating stirring blade (1503) is used for fully stirring the mixed liquid in the treatment shell (2) to enable the wastewater and the flocculating agent to be fully contacted, so that the reaction between the wastewater and the flocculating agent is quickened, and meanwhile, the floccules generated by the reaction of the wastewater and the flocculating agent are upwards moved by utilizing small bubbles generated by the decompressed water, so that the generated floccules and the mixed liquid are layered to facilitate the subsequent treatment, and after the wastewater treatment is finished, the worker opens a discharge pipeline of the treatment shell (2) to discharge the treated wastewater.
